Linux swatch command

Linux 命令大全Linux Command Encyclopedia

The Linux swatch command is used for system monitoring programs.

swatch can be used to monitor system log files and execute specified actions when specific events are detected. The events monitored by swatch and the actions corresponding to those events are stored in the swatch configuration file. The default configuration file is .swatchrc in the user's home directory. However, in Red Hat Linux's default user home directory there is no .swatchrc configuration file. You can copy the /usr/doc/swatch-2.2/config_files/swatchrc.personal file to .swatchrc in the user's home directory, and then modify the events to be monitored and the actions to be executed in .swatchrc.
